2011-03-16T15:22:41+00:00

* 'for-2.6.39' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/percpu:
  percpu, x86: Add arch-specific this_cpu_cmpxchg_double() support
  percpu: Generic support for this_cpu_cmpxchg_double()
  alpha: use L1_CACHE_BYTES for cacheline size in the linker script
  percpu: align percpu readmostly subsection to cacheline

Fix up trivial conflict in arch/x86/kernel/vmlinux.lds.S due to the
percpu alignment having changed ("x86: Reduce back the alignment of the
per-CPU data section")

Drop redundant __param section for CRISv32.

2011-02-23T16:00:47+00:00

The __param section is already brought in by RODATA above.

percpu: align percpu readmostly subsection to cacheline

2011-01-25T13:26:50+00:00

Currently percpu readmostly subsection may share cachelines with other
percpu subsections which may result in unnecessary cacheline bounce
and performance degradation.

This patch adds @cacheline parameter to PERCPU() and PERCPU_VADDR()
linker macros, makes each arch linker scripts specify its cacheline
size and use it to align percpu subsections.

This is based on Shaohua's x86 only patch.

CRIS: Fix alignment problem for older ld

2010-08-04T16:30:01+00:00

CRISv10 uses a pretty old ld, which does not allow ALIGN(0),
(It becomes . = 0;) so instead we align to 1 byte.

CRIS: Discard exit.text and .data at runtime

2010-08-04T12:10:04+00:00

This allows us to handle references from __bug_table.

drop explicit include of autoconf.h

2009-12-12T12:08:15+00:00

kbuild.h forces include of autoconf.h on the
commandline using -include - so we do not need to
include the file explicit.

linker script: unify usage of discard definition

2009-07-09T02:27:40+00:00

Discarded sections in different archs share some commonality but have
considerable differences.  This led to linker script for each arch
implementing its own /DISCARD/ definition, which makes maintaining
tedious and adding new entries error-prone.

This patch makes all linker scripts to move discard definitions to the
end of the linker script and use the common DISCARDS macro.  As ld
uses the first matching section definition, archs can include default
discarded sections by including them earlier in the linker script.

ia64 is notable because it first throws away some ia64 specific
subsections and then include the rest of the sections into the final
image, so those sections must be discarded before the inclusion.

defconfig compile tested for x86, x86-64, powerpc, powerpc64, ia64,
alpha, sparc, sparc64 and s390.  Michal Simek tested microblaze.
